'GAS-ENGINE STARTER.

SPECFICdTIONfoI'm-ng part of Letters'latent No. 768,506, dated August 23, 1904.

Application lod yAuguri. 24., 1903.

Be it known that-I, GUSTS S. BILLMAS. of

Indiana. .have invented a certain new and useful (J'sEngie Starter; and 1 do hereby declare that the following is a full, clear, and exact description thereof. reference being had to the accompanying drawings, in which like nLmerals refer t like parts.

The object of this` invention is to provide certain improvements in automatic Starting mechanism for explosive-enginesof a gaboleneA or other type over what is sety forth in m v formerappl ications for Letters Patent, Serial No. 121,406. tiled August. :28, 1902, and Serial No. 157,953, filed May Q0, 1903.

The device shown und described herein further siznplilies the construction, as will appear from the accompanying drawings andthe following description and claims.

ln the drawings, Figure 1 is-a plain view of my improved starting mechanism in place with the lid oil' and the main drivingedmft broken away,`1mrts being broken away and parts in sect-ion. Figs. 2, 3, and 4 are plan views, on an enlarged scale, of a portion of the clutch mechanism, showing the parts in different positions during the operation. ,Fig 5 is a' central vertical sect-ion on the line 5 5 i of Fig. 2. showing also a part of the main of a portion of the device with parts broken away to disclose the clutch mechanism. Fig. 7 is a Avertical section oft-he device :1s shown in Fig. 1 on a line just inside the large spurgear'and grooved disk. parts being broken- -awa'x Fig. 8 is a detail view showing the master-bar in side elevation and other parts in cr0.=ssection, pax-tkbeing broken away.

This device is adapted to be attached to an automobile or similar machine which may be driven h v an e.\:plo.-five-engine.

1U is 1hrmuiu shaft, driven by the gas-engine and muy be one of the axles of the automobile. The frame 1l is connected in anyl i desir-H1 \\:i v with the engine or machine` it I lreing rigid with relation to the shaft 10. Then-fore this device will operate the gas-engine hyolwraling the yshaft, 10` as heretofore i explained in my said former applications, and' l`slidable on the shaft 10, assetfortb in Serixl'o. 170,589. (Fa model) l also the gas-engine winds or places the auto mutig: starting mechanic!)y in position for operation through said shaft 10. A pinion 12 is loosely mounted on the shaft 10 to mesh with the gear 13, that is loosely mounted on the spindle 14, which is rigidly secured to the frame 11. The gear 11,'meshes with another gear, 15, that is rigidly mounted on a counter-sha1' t 1 (i, whereby said shaft isdriven from the mairi'shaft.4 1U. The shaft 16 carries a spring 19 onone end ot' it, which said shaft winds. The spring i. helical, being fastened entrsill;v to said shaft and at its outer end to the pin 20 in the frameconstruction the ordinary operation of a gmsengine will drive the grfers and shaft specified and wind the spring 19. shown in Eig. l.

The windingr ofthe spring is automatically stopped b v the following construction: A muster-bar21 extend longitudinally of the de vice and over the shaft 16. The rear end of the har is yoked to4 rry parallel arms or places 22, which lit astri-ie the clutch-box 23, that surrounds the main shaftl 10, one erm 22 being above the clutehbox. as shown, and the other arm' being below as appears in my last application above mentioned.4 Each of said arms 1s Icutout, as shown in Figs. 1 to 4, to

'ith the foregoing form an openingr or slot emendng longitudinail;r of the arm. At the rear end of said .opening thereis an inclined shoulder 24.-, thatis slightly to one side of a central line drawn longitudinally through said arms. The mas ter-har 2l isA reciproted by reason of the pin 2T extending inward from the arm 28 on said bar an l litting in a helical groove in the disk 18. "hen the disk 1i! revolves in-one direc tion, therefore` the master-bar 21 will be moved rearwardly, andas said disk revolves in the opposite direction said master'bar will be moved forwardly- Tue grooved disk 18 is placed on 4one side or rather forms one side of the gear 1i". which is tothe Shaft 16.

Said gear 17 meshes with the large gear 31,

said apnu-nt. with either the wheel l2 or the wheel 31.1

That sleeve or clutch member 32' has pins .26

extendingr radially from opposite sides t-lifzrcof. as shown in Fig. 8. Said pins 26 extend tlirough transverse slots in the clutch-box 23',

so as to he. movable longitudinally o f the shaft 10 and independently of said elutel1- box.

Said clutch memher32is movedinto engage` ment with one or the other of the wheels 12 and 31 h v the reciprocatory movement of the master-bar 21.V Said bar 21 .is guided in its movement on the clutch-box QB-by the guidelug's 31. which extend upward from said box. Upon both the'arms 22 of the master-baraplatc 4U is secured, which covers the openingS in said' arms, and from said plate 40 a tongue 41 extends inward into the opening in the arm 12, as appears in Fig. 5. This tongue 'appears in. cross-section in all the other 5gures1 beingr cut just below the plate 40 in order to disclose the mechanism below. The tongue 4,1 is placed on amiddle line extending longitudinally of the arms 22 vfrom t-he master-bar and Ais beveled at each end, asv

shown. The bevel at thc rear end isY parallel with the inclination of the shoulder 24 in the armhof the master-barand farenoughaway f rom said shoulder to permit the pin 26 from in the opening in the'arms 22 of the mster-bar both at'the top and at the'bottom there are mounted. two inclined clutch-throwing blocksV and 6, the;v being of the same thickness as the 'arm 22 and re mounted respectively on the s ha'riks 47 and 48, that loosely fit in hoi'cs bored in the arm 22` as appearain Fig. 1, so as to he longitudinally movable and are pushed outward by the spiral springs i9, as

shown. Th(l clutch-throwing blocks 45 and 46 are therefore always normall)r forced towardcach other'nnd against the' tongue 41A, excepting when the clutch-pin 26 may push one or th'e other away. At the other end of the masterbar there is a guide-rod '50, extending through the frame and also the cap- 51.

There' is also a looking-pm 36; that is slidableand held in engagement. with the periphery of -the disk 18 by the spring 52. 1t is'adapted tn engage a' notch in` the periphery,v of the disk 18, which notch is not shown here, but appears in my last application. pin-211' is parallel with the guide-rod 50, and both said pin and said'rod are provided with opposiulv-loeatod notches 53., adapted to be engagul hy a'loosely-mounted and slidahlc lock-holt 54, mounted in the framework, -as shown in Fig, 1. The posit-ion of" the parts instelt-.scribed is such that said bolt 54 lwill lockonly one at aA time. The bolt M is for the purpose of holding the locking-pin 36 in' its disengaging position during the movement of the master-har` The operationof the device with nl) pressuccessively.

4gagement with the gear-wheel 31.

Said locking? of the spring then ceases.

fthe pin ent imprvenn-nt is as follows: As shown in Fig. 1, the device-has inst been svt in opera'- tion for starting tine engine. 'l`htl pin 25V lmb just been drawn, releasing the spring. which is unwindin;5..:nd the 'master-har has just Started to the rear. the noti-h .'Il in the. rod 5o having moved somt-what'away from the end of the locking-rol :'41 The slight. rearward movement of tlxe'nmster-bar that has just taken place has` moved tht` tongue-11 likewise rearward. and -its rear oblique fak-e has pushed the pin l26 from to the position shown in Fig. 1` and therefore moved the clutch mem-her 32 from the midway inoperative position toward and in engagement with the teeth on the wheel 31. Asi the spring further unwinds the gears 17 and the position shown in Fig. 2

31 will actuate the main shaft 10 and startthe engine. v'As the master-bar moves rearward the arm 22 assumes the. position with relation to the'pin 26 that is shown in Figs. 3 and 4 Said pin engages the block 46 and pushes it back against the action of its spring from the .position shown in Figr'to that shown in Fig; s1, the lat-ter position beingreaiched-about the time the niainsprint; 19 is unwound. tension ofuthe sprini,r 49 this tirnenecom'c so great to die-im block 4t. to th-roiwtlie'piif 26 and bring the cinch member lout of vn-4 At the same time it throws said clutch member and pin over into engagement with the pinion 12. and the further op 10 by the engine causes the mechanism to wind up the spring 19. As said spring 19 is Wound the disk 1r. .with the groove in it1 will cause the master-bar to be moved forward or to the right. longitudinally rcmthe position shown in Fig, 4 to that shown .n Fig. 2.

almost reaches its limit. of movement the ineration of the main shaft As the master-liar clined face o f' the block 4.5 engages the pin 26w and throws it and the clutch .member 32 away from the pinion 1i'. (o the middle inoperative position, (Shown in Fig. 2.) The winding B v that time the notch 53' in the master-bar vrod 50 has come opposite the bolt 54, so tlmtlsaid iockingdiolt can enter the notch in the rod 50.. The spring 52 on the pir. :i6 will then ,force said pininto engagement with the disk 18 and hold itin a lockcdpositon. The. jxnechanism is now inoperative and will remain so until it is desired to start the engine again, when the lockingpin 36 is released and the same operation is repeated as has been described.-

[i maybe a-.lded that the block-46 willtilrow 26' and ci uteh `member 32 over toward the pinion 12 fromftlu position shown in Fig. 3 as soon as the 'engine tires. and theriifore the strain is taken oli' the-gear 31, for then the the block. -16 may he forced hack as far as in Vig, 4, when the. increased ten ion of the.
